Cheesy Au Gratin Potatoes Recipe

Melt the butter in a large skillet or pan on the stovetop over medium heat. Add the garlic and cook for 1 minute, stirring continuously. 

Sprinkle the flour over the butter and whisk while cooking for 1 minute. 

Slowly pour in the half and half and whole milk, while whisking, until it is completely incorporated with the flour mixture.

Continue to cook for 3-5 minutes, while whisking occasionally, until the sauce starts to thicken.

Remove the sauce off of the heat and whisk in the salt, pepper, and paprika.

Using a mandolin slicer or a sharp knife, slice all of the potatoes into approximately 1/8 inch thick rounds. 

Place the sliced potatoes in small stacks on their sides, in alternating directions, in the prepared baking dish.

Sprinkle the cheddar cheese over the sliced potatoes and then pour the prepared cream sauce over the potatoes and cheese. 

Using a spoon, gently spread the sauce over the potatoes, so it covers it completely and starts to seep down into the crevices. Sprinkle the top of the sauce with the parmesan cheese.

Bake the potatoes in the preheated oven for 60-65 minutes until potatoes are fork-tender and browned on top. Let the potatoes sit for 15 minutes before serving.
